FEELING MECHANISM FOR MACHINES FOE, PUNCHING CONTROLLTNG BANDS.

Application filed April 15, 1928, Serial No. 182,328, and. in Germany June 6, 1925.

This invention relates to punching machines for punching cont-rolling bands designed for controlling a line casting machine, said punching machines being of the type described in our application Serial Number 721,524. This invention has for its object to improve the feeling mechanism described in said application so that only a few levers and a very simple mechanism easy to survey are necessary.

\Vith this object in view the marks on the circulating elements consisting of lateral incisions are not all of the same depth but of different depths so that by the position and the depth of the incisions the desired combinations can be obtained. in this case four feeling elements are sufficient for adjusting the punching mechanism.

Spring-controlled feeling elements are designed to engage with the incisions in the circulating elements and to regulate, by thei movement, the amplitude of the oscillation of the punching levers. These punching levers are brought onto the path of a punching frame if they are in a certain position and they are carried along in this position by the punching frame and punch holes into the controlling band. The punchings at dif ferent points of the controlling band correspond to certain characters which appear on the key board of the punching machine.

A further object of the invention is, to control the feeling elements by the separating slide. The function of this separating slids, as stated in our prior application Serial Number 721,524, is to push the elements separated from an assembled line singly towards the distributing spindles which convey the elements to the correspondmg magazines. 7

According to the invention the feeling levers bear against an abutment on the separating slide and are pressed onto the same by the action of springs. If the separating slide is moved the feeling levers can engage with incisions, preferably arranged in the lower edge of the circulating elements, and adjust the abutments for the operation of the corresponding punches. lVith this object in View the stroke of the separating slide is subdivided into two steps. At the first step it advances only so far that .the feeling levers engage with the incisions of the circulating elements, at the second placed by a movement of the feeling levers so that an aperture comes into register with its bolt, this bolt traverses the band in moving a corresponding punch lever so that it gets onto the path of the punching frame. As soon as this frame is pushed in a downward direction by a separate mechanism of the machine it drives the punch through the paper band.

The improved feeling mechanism is shown, by way of example, in the accompanying drawing in which Fig. 1 shows in side elevation the distributing mechanism.

Fig. 2 is an end view of the separating slide and of the head of the feeling levers.

On the shaft 1 connected with one of the distributing spindles 13 a curved cam-surface 3 is arranged which controls the os illating movements of a lever 2. This lever 2 is permanently pulled to the left by the action of a spring 4 attached to the machine frame (Fig. l). .Vith lever 2 a second spring-controlled lever 5 is connected which carries on its front end a separating slide 6. In the separating slide 6, which is submitted to the action of a pressure-spring 7, the heads 8 of the feeling levers 12 are commodated so that they bear onto a shoulder 6 on the inner side of the separating slide. These heads 8 have each at the top end an extension 8 of approximately the same thickness as a circulating element. ()n the lever 5 a guide fork 9 1s hingedly mounted the arms of which engage over a bolt 9. On the guide fork 9 an abutment surface 10 is arranged against which'bears the lower end 11 of a locking lever 11. The other end 11 of this locking lever strikes onto the lower lugs of the circulating element 0, as can be seen from Fig. 4c.

The feeling levers 12 are pivotally mounted on the machine frame and they are connected each one with a rod 14. These rods 1.4. are pulled downward by the action of springs 16 so that the heads 8 of the feeling levers have a tendency to move in upward direction.

The operation of the elements of the mechanism which have been described is as follows :By the curved cam surface 3 the lever 2 is operated which lifts the separating slide 6 through the intermediary of lever 5. As the heads 8 of the feeling levers 12 are under the action of the springs 16 they move together with the separating slide 6 and engage with the corresponding incisions b of the circulating elements a resting upon the surface 1. The end 11 of the locking lever 11 supports the elements so that they cannot be raised by the feeling lever. The locking lever 11 is prevented from rotating by the abutment face 10 of the guide fork 9. The extensions 8' of the heads 8 penetrate into the incisions b of the circulating elements down to the end. The lever 2, and through the same the separating slide is again operated by the second step of the curved cam surface 3 so that the abutment of surface 10 releases the locking lever11 and the circulating elements a can be raised by the upper edge of the slide 6 into the path of the distributing spindles 13. (Fig. 4.) The curved cam surface 3 drops again and the separating slide (ireturnsby its shoulder 6 the heads 8 into the initial position.

If the drivingmechanism for the feeling levers has to be thrown out of gear for the reason that there are no circulating elements in the distributing mechanisms, or if the transmission slide which conveys the line of assembled elements for the elevator into the mechanism is pulled back, the following arrangement is provided:

A lever 50 pulled to the right by the action of a spring 52 is pivotally mounted on a bolt 51 fixed in the machine frame. With this lever 50 a bow 53 is connected, as can be seen from Figs. 1 and 3, the curved front end of which engages with a notch of the guide piece 57; the end of the bow is in the path of the rising circulating element (1.. The lower end 54 of lever 50 rests, in the normal position, upon the surface 55 of the feeling lever 12 and prevents thus the upward movement of the left lever arm. Close to this surface 55 a notch 56 is arranged on the feeling lever 12.

The operation of this disengaging machanism is as follows By the spring 52 the top portion of the lever 50 is pulled to the right and the bottom portion 5% to the left so that this bottom portion prevents the movement of lever 12. As soon as a circulating element a is pushed into the guide piece 5 by one of the conveying slides shown in our prior application Serial Number 721,524, it pushes the bow in front of it, the spring being thus put under tension. The end 5% of the lever 50 is thus brought into register with the notch 56 of the feeling lever 12, so that this feeling lever can move upward as soon as the separating slide 6 is raised so that the feeling. levers can. come into engagement with the circulating elements (4.

If there is no circulating element in the mechanism or if the conveying slide is just pulled back the feeling levers 12, if these disengaging means were not provided, would move with the separating slide and useless perforation con'ibinations would be produced in the controlling band.

The transmission of the movement or of the extreme position of the heads 8 of the feeling levers 12 is controlled, as has been mentioned above, by the rods 14 (Figs. 5 to 8).

The lower ends of these rods act upon levers 15 which are connected with adjusting bands 17. These bands 17 have notches 18 and they are guided in corresponding slots of the machine frame. In front of the adjusting bands spring-controlled bolts 19 are arranged.

As soon as the adjusting band is shifted, if the lever 12 is in the extreme position, so that a notch 18 comes into register with one of the bolts 19, this bolt can traverse the adjusting bands 17 if it is pushed by one of the levers 20 towards said adjusting bands. The punch lererr'; 20 are controlled by springs 21. which, as can be seen from Fi 6, have the tendency to move said levers to the right. The springs 21 are much stronger than the springs of the bolts 19.

If one of the springs 21 can push the lever 20, and consequently the corresponding bolt 19 through the adjusting bands 17, this punch lever 20 gets into the path of the punching frame 22 and is drawn along by this frame. as soon as it is depressed by a lever 24. moving in a curved guide groove of the main shaft 23. The descending movement of the punching frame 22 is transmitted through the intermediary of lever 20 upon the punch 25 which thus punches a hole into the controlling band 26. To a certain extreme position of the levers 12 corresponds therefore a certain punching of the controlling band.

In order to lock the adjusting bands 1'7 in their extreme position a separate mechanism is provided which consists of a twoarmed lever 28 driven from the main shaft 23, and connected with a rod 20 which carries a lever 29 which has a ratchet tooth. This lever 29 is controlled by a spring 6]. and released by the cam of shaft 23 through the intermediary of rod so that it is free to follow the pressure of spring 61, as soon as the levers 12 have assumed their extreme position.

In order that the punch levers 20 do not press permanently onto the bolts 19, but only if the feeling off of the circulating elements a takes place, they are normally pushed to the left by an abutment 68, as can be seen from Fig. 6. This movement is initiated by the shaft 1 through the intermediary of a cam 33 and transmitted by the lever 8% upon an adjustable abutment 66 of the lever 65. This lever is, like the punching mechanism, mounted in a stationary frame 62 and its movement is transmitted upon a lever 32 which consequently executes an oscillating movement, so that at certain periods the abutment 63 and through this the punch levers 20 are pushed to the left.

In the new distributing mechanism the feeling off of the circulating elements can take place during the separatin of the several elements from the line OI assembled elements. No special device is necessary for this purpose and it is further not necessary to bring the circulating elements separately into a special position for feeling off. At the feeling off the circulating elements are held in all directions so that no special means are required to support the elements from different sides during the feeling off. The mechanism works with a few levers only so that its effect is secured and easy to survey.
